Filed: 1953-03-30
Abstract: 724,330. Refrigerating. CARRIER ENGINEERING CO., Ltd. March 30, 1953 [Sept. 30, 1952], No. 8797/53. Class 29. The storage space 12'of e.g. a lorry or trailer is refrigerated by a system comprising in series a continuously-running compressor 2, a condenser 3, a receiver 5, a liquid line 7, an expansion valve 8 and an evaporator 6 and when the temperature of the space 12 is sufficiently low, the compressed gas is led through a by-pass pipe 16, a valve 17 and a superheatremoving coil 18 back to the suction of the compressor. Valve 17 is normally held-closed by condenser pressure acting through a pipe 19 on the underside of the valve diaphragm 22. When the desired temperature has been attained, it is detected by. a bulb 13 which causes a solenoid-operated valve 10 in pipe 7 to close whereupon the evaporator pressure reaches pipe 19 by way of a capillary by-pass 30 around the expansion valve 8 or by a small orifice in the expansion valve seat. This lower pressure in pipe 19 allows a spring 23 and atmospheric pressure to open the valve 17 to allow the refrigerant to pass from the compressor discharge to ,the suction.

Patent GB-1070742-A (GB)
Title: Diffusable substrates and diffusion processes
IPC: C23C16/40
Filed: 1964-03-04
Abstract: At least part of a body of a compound semi-conductor material is covered with a deposited layer of an oxide material prior to diffusing impurities into it.  The oxide layer is said to be thick enough to prevent deterioration of the surface of the body by volatilization of the material. The impurities may be diffused through the oxide layer or be deposited with the oxide layer and then diffused in.  The oxide layer enables a uniform diffusion front to be formed.  The oxide layer is preferably of silicon whilst the compound semi-conductor material may be GaAs, InAs, Pb Te or AII BVI compounds.  The dopant impurities may be Mn, Fe, Mg, Zn or Sn.  In one embodiment Fig. 1 (not shown), the oxygen layer is deposited by the pyrolytic decomposition of tetraethoxysilane is a stream of oxygen and nitrogen. In another embodiment Fig. 2 (not shown) cathodic sputtering in oxygen employing a silicon cathode is used to form the oxide layer.  If an impurity is to be deposited together with the oxide layer, an additional cathode e.g. of zinc, or a cathode of both Si and the impurity, is used.  Both open and closed tube techniques may be used to diffuse in impurities.  A planar transistor may be made either by depositing an oxide layer having a thin region and diffusing impurities in through the thin region Fig. 12 (not shown) or by depositing an oxide layer containing the impurities on part of a semi-conductor body, covering the body and oxide layer, with another oxide layer and heating the covered body to effect diffusion Figs. 15a to 15e (not shown).  A mesa diode Fig. 16c (not shown) may be made having Au-Zn contacts on the p-type mesa region and Au-Sb contacts on the base. Another transistor Fig. 11 (not shown) has ohmic collector contact of Pt soldered to it by Au-Se ohmic base contact Au-Zn and an alloy emitter region of Au-Sn with an emitter contact of Pb. Zn-doped GaAs having a junction therein made by diffusion through the deposited oxide, is cut along the (110) plane to give lasers of low current threshold and current density.

Title: Method and apparatus for detecting components of a gas mixture by ionisation and measurement of the ion current
IPC: G01N27/66
Filed: 1963-03-11
Abstract: 1,037,742. Discharge apparatus. ATLAS MERS-UND ANALYSENTECHNIK G.m.b.H. March 11, 1963 [March 10, 1962], No. 9592/63. Heading H1D. [Also in Division G1] To detect components in a gas it is ionized at two or more different energies so that the ionization probabilities of the different components are in different proportions in the different ionization chambers. Thus the total ion currents may be used to evaluate the proportions of the components in the mixture. In the embodiment of Fig. 1 an electron beam passes through a first ionization chamber 6 and then has its energy increased before passing through a second ionization chamber 7. The magnet 14, 15 serves to focus the electron beam. The apparatus may be used to determine the proportions in a binary mixture from the ion currents to collectors 19 and 20. The apparatus may also be used as a leak detector in a high vacuum apparatus. In this case the energy of the electron beam in the first chamber is preferably below the ionization value for the probe gas such as helium and the energy in the second chamber is arranged to give as high an ionization of helium as possible. The bridge circuit 23 is first balanced in the absence of helium so that when the apparatus is sprayed with helium a very sensitive response is produced to a leak. In another embodiment, Fig. 2 (not shown), the ionization chambers are connected between a gas chromatography column and a mass spectrometer. This arrangement uses parallel electron beams of different energies in the two chambers.
